There’s still no word on which Plymouth County community has the first confirmed local case of swine flu, and Brockton’s public health director believes that’s a problem.

“You’ve got to have people in your town know what’s going on,” said health department executive director Lou Tartaglia. He urged the community with the case to issue a press release and public advisory on the situation.

On Friday, the state Department of Public Health said a 33-year-old resident of Plymouth County has been confirmed with a case of swine flu. (The department says it originally reported the person’s age incorrectly, as 34.)

But the state declined to release the community where the case originated, saying this could lead to a violation of patient confidentiality. Officials said they’d leave it up to each community to release details about confirmed cases.

As of this morning, however, no community has contacted The Enterprise to report having the confirmed case.

Tartaglia believes this is the wrong approach. Residents should know that all the appropriate steps have been taken to contain a case of swine flu in their community, he said.

“I don’t think one case would cause a panic. People should be aware that their city or town has a case,” he said.

The state’s tally of confirmed cases remains at six, though the number of cases nationally has climbed to 226, according to the federal Centers for Disease Control.

Tartaglia said he also hasn’t received any word on two potential swine flu cases reported to the state by Brockton-based Signature Healthcare. Tartaglia said he assumes the cases, which were reported last Tuesday, were not cases of swine flu.

State public health officials have said they will only comment on confirmed cases. Due to the hundreds of test samples being sent into the office, it would be impossible for the state to release information every time a case is ruled out, said Jennifer Manley, a spokeswoman for the Department of Public Health.

Despite signs that swine flu is a diminishing threat, Tartaglia says “it’s too early to say this thing has subsided.”

He noted that flu viruses do not like heat and humidity and typically fade in summer, and tend to re-emerge when colder temperatures arrive.

“This thing could resurface and be more resilient than it is now,” he said.
